The Role Of Potassium Fertilizer

Promote the activation of enzymes The activation of enzymes is one of the most important functions of potassium in the process of plant growth. Potassium has been found to be an activator of more than 60 enzymes. therefore. Potassium is closely related to many metabolic processes in plants, such as: photosynthesis, respiration, and synthesis of carbohydrates, fats, and proteins.
Promote photosynthesis and transport of photosynthetic products ① Improve photosynthetic efficiency; ② Regulate the opening and closing of stomata, control the entry and exit of CO2 and water; ③ Promote the synthesis of carbohydrates and accelerate the flow of photosynthetic products.
Promote protein synthesis ①Promote the uptake and operation of NO₃, the key component of protein synthesis; ②It is closely related to the process of protein synthesis.
Enhance the stress resistance of plants Potassium can reduce soluble amino acids and monosaccharides in crops, increase cellulose, and thicken cell walls; Potassium accumulates in crop roots to generate osmotic pressure gradients that can enhance water absorption; Potassium can make crop leaves dry when there is drought and water shortage The pores are closed to prevent moisture loss. Therefore, potassium can enhance crop resistance to disease, cold, drought, lodging and salt.
Improve the quality of crop products Increase the protein content of grain crops, the crude fat and palmitic acid content of oil crops, the starch and sugar content of potato and sugar crops; increase the fiber length, strength, and fineness of fiber crops and cotton; adjust the sugar content of fruits Increase the acid ratio, increase the content of vitamin C; improve the shape, size, color and flavor of fruits and vegetables, and enhance their storability.
